SYMPTOMS
========

You are unable to install the updated driver for the DEC DC21040 PCI Ethernet
adapter (DC21X4.SYS) included with Windows NT 3.5 U.S. Service Pack 2.

CAUSE
=====

The file name of the DEC DC21040 driver included with Windows NT 3.5 is
DC21040.SYS. Because the file name is different than the file name of the DEC
DC21040 driver included with Service Pack 2, the driver is not updated when you
install Service Pack 2.

Service Pack 2 does not include an .INF file that can be used to install the
DC21X4.SYS driver. The INF file included with Windows NT 3.5 cannot be used to
correctly install the DC21X4.SYS driver.

RESOLUTION
==========

The DC21040.SYS driver included with Windows NT 3.5 is version 6.0. DEC has
released version 6.3 of this driver. Please contact DEC to obtain this driver.

STATUS
======

Microsoft has confirmed this to be a problem in Windows NT version 3.5. We are
researching this problem and will post new information here in the Microsoft
Knowledge Base as it becomes available.
